Question

Two equal sides of a triangle are 4 m less than three times the third side. Find the dimensions of the triangle if its perimeter is 55 m​

Answer 1

Answer:

23m

Step-by-step explanation:

Let x be the third side,

Then (3x−4) will be length of the equal sides.

As per the question-

55=x+2(3x−4)

55=x+6x−8

55=7x−8

55+8=7x

63=7x

9=x

Therefore, the third side = x=9m.

Hence, the equal two sides = (3x−4)=(3×9−4)=27−4=23m each.
